cit-nuance.

To all whoim it may concern: 7

Be it known. that we, Gno'uen B. VoN Boom; and Enwm F. INoLEs, both citizens of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

Our invention relates to an atomizer or burner, which is especially designed for use with heavy crude oils which are largely used in connection with locomotive and other boilers.

It'consists in an arrangement of a steam and superposed oil passage with a plurality of connections with the latter, means for inspecting and cleaning the steam passage and so that the apparatus may be used where it would be otherwise impossible to employ it, also steam conduit connections.

As shown in the, drawings, the device is castin a single iece having in the upper part an oil condult 2 and in the lower part a steam conduit 3. The oil conduit has a substantially rectangular opening 2 atthe front; this opening having its. greatest length horizontal and its transversedepth vertical. The upper part or roof of this conduit is curved downwardly, as shown at 4, and the floor is similarly curved, as

. shown at 5.

The steam conduit has a narrow, transversely elongated slit. 6, through which steam is discharged, and the oil flowing easily over the curved front, meets the sheet of steam upon which it is received and upborne, and by the velocity of-which it is thrown outwardlyand so finely atomized.

that the combustion is greatly improved.

,7 is a lip or plane extending forward from the steam discharge openings slightly below and substantially parallel with the laneof discharge of the said opening. This lip or S peeification of Letters Yatent.

surface is here sh-own as transversely corrugated or otherwise formed with an irregular surface, and'in the present case the corrugations are shown extending in straight lines transverse tb the plane of discharge. The front edge of the lip may be segmentally curved, as shown at.8. I

In order to-confine the discharge and prevent its flowing oil the sides of the lip and also to prevent the oil from being dispersed too widely, we show sides or extensions 9, upon each side of the lip, and these sides or extensions have a height equal to or above the upper edge of the steam discharge slit,

so that the full force of the steam, when first delivered, is exerted directly forward;

the side expansion only taking the steam and oil have passed front ends of the raised sides.

In order to utilize our apparatus in places where it is impossible to introduce the oil from above, we have formed feed openings 10 and 10, one located above and the other below the structure. The opening 10"extends upward from below into the lower part of the conduit 2 and has its axis slightly ace after eyond the in advance of the axis-of the opening 10,

and this provides for a sufficient channel or space upon each side of the walls of the o ening 10 so that steam introduced t rough the central passage 11 at the rear of the device may pass around these walls and enter the mam steam conduit 3. \Vhen the oil is thus introduced from below, the upper opening 10 is closed by a screw plug which fits and hermetically seals it.- Thus 'we are enabledto employ the single structure at any point, whether the oil be introduced from above or below; the oilalways being located above the steam conduit. With this construction it is difficult to obtain access to the steam conduitto see that it is clean or toremove core sand or other obstructions that may'form in a casting of this description. We have, therefore, shown openings with closing screw plugs, as at 11,

upon each side of the rear of the device, so

that the-line of vision through these .openings will pass upon each side of the walls of the opening 10; thus we are enabled to inspect the interiorof the steam passage by I allowing a light to enter through the opposite end, and if obstructed, a tool may be in-v troduced to clean the conduit out and make it fit for use.

Having thus described our invention,

what we claim and desire to secure by Letters Patent is- An oil burner, comprising a metal conduit with parallel steam and oil passages, the lat, ter located above the former, said conduit having means for discharging the steam and 7 oil, and having a'plurality of Vertical inlet passages connecting with the rear of the oil passage, one from above and the other from 10 below, a centrally located steam inlet-at the rear of the conduit, the wall of the lower vertical inlet passage being projected across the path of and intercepting the incoming steam and serving as an abutment for cliverting the path thereof, said abutment forming between itself and the inner walls of the conduit side passages through which the divertedportions of the steam may pass, and plugged openingsleading to said passages.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
